I think when you know what you are going to wear, it fits and it's great material, then you feel confident in it.

I try not to hit a swing volley and run back. So my swing volley is kind of that transition to the net. It's been one of my favorite shots ever since I was young.

You have your bad moments in your career and your good moments. And it's been a good ride so far, but it's not over yet.

I don't have to follow any special diet or count calories. I try to eat healthily and before a match I load up on pasta and salads. But I pretty much do what I want.

I don't need many things. I don't need glamour and attention to be happy. I'm very happy being settled and working my butt off and trying to win grand slams.

I don't get to do as much sightseeing as I would like to.

I'm 17 years old and there are many great things ahead. If I don't win the U.S. Open this year, it's not going to be a disaster in my life.
